The dermatologist's office called yesterday with the results, and, sure enough, I have a basal cell carcinoma. I'll get it removed Monday morning, then go to work. I hope there is something better to do that just put vaseline on the wound, because that is what he is having me do for the wound from the biopsy, and, man, I am getting sick of my shirt sticking to the oozy scab.
I'm not worried about the surgery itself. It should be fast and hopefully completely remove the offending skin. I've had a basal cell carcinoma in the same spot before, but it was treated with topical chemicals rather than just getting rid of the damned thing.
